I built my deck this weekend on deck blocks, and it was a complete success. For anyone who is considering this method, go for it. This deck is just as stable as a normal concrete-footing deck.

Any questions, just post them here and I will help you out.

Question: I live in Canada in the Ottawa area. The soil in my yard has a fair amount of clay. Is it okay to use deck blocks to support a new deck that will be 16 x 12 feet and 4 feet high?

Some have suggested that a maximum size for deck blocks would be 12 x 12. After that it would be subject to twisting too much as the ground shifts. What do you think is the maximum size of deck where it would be okay to use deck blocks instead of using concrete pillars?

My deck is much larger than 12x12, and it will not move an inch, I guarantee it. My deck is not more than 36 inches off the ground, so your height will be more than mine...however, the web site suggests using blocks UP TO 60 inches, so you should be fine.

Putting these on clay will not be a problem.

Check out the site and do some research, their plans are VERY helpful. www.freedeckplans.com

Good luck!

PS, don't be afraid to ask questions on their bulletin board either, Deckman is very helpful and will get back to you for sure.
